To all whom it may concern:

Be it known that I, STEWART R. MCKAY,' States residing. at ClevelandHeights, in the county of Cuyahave} invented a certain new and usefulImprovement in Demountable Rims, of which the following is a full,clear,'and exact description.

This invention is the outcome of efforts to produce a demountable' tireholding rim more cheaply than anynow in use can be produced. v 7' A tireholding demountable rim whieh embodies all thecharacteristics ofinvention is composed-of a pinrality of se such arcual ength that theymay be easily formed by the stamping process. These sections areformedywith interlocking parts a wheel to a It will be obvious, however,thetmax? of at inview of awheel rim in which; the present by 'whichtheir relative and by means of which t ey may be separas bly locked tther and likewise locked onto ifiiich they are fitted.

the novel and useful characteristics vention embodied in the rim asshown are capable of embodiment in a. rim which is composed oftwqsections onlyd.regardless of ow they are made, provide the'ends of=sai sections are constructed for cooperation in substantiallythe'manner disclosed.

The invention consists in the construction and combination'of partsshown in the,

drawin s and hereinafter described and definitegy pointed out in theappended claims.

then bent down to form a tongue 12, which, after bein so bent, will beat substantially right ang es to the base" and parallel with the outerface of the wheel felly 30 on which the complete rim is to-be secured.This tongue at its free end is formed with an outwardly extended flange13; and the ton us also has a hole 14 for the reception 0% alfallzprally extended bolt 31 carried by the lose to the extrenf end ofeach belled outer section end, a ongue 22 is pressed down from the base17 thereof, therebyle'aving a hole23. When two ad acent sections areassembledas shown, the tongue 12 passes through this hole 23,. and thesides of the tongue referably eng'a e the ends of the hole. The tongue22 wil lie-outside of, and will be substantially parallel with thetongue 12, and the end of tongue 22 will roperly shape toifit' and willengage the ange 13 on ton e 12., .The tongue 22 will likewise have a olthole 24 through itin alinement with the hole 14in the tongue 12. Whenthe parts have been so assembled the overlapping end'of thebase part 17of the inner-sectionend. will lie ,over and will cover A. n 1 "up ofparts having substantially. ibed constructionjwhen assembl they-mannerdescribed, will hold its sh with a tire thereon, so that said .rim and emay be put'onto 'and taken off of a wh if the rim iscarefully handled.It is preferable, however, to have certain overlapping section endsrmaneritly secured together. Preferentially five of the sec ions are sopermanently secured together by spot-welding their overlappingportion's. T e remaining section is like section 20. The rim, therehenthe sections are so connected, bein efl'ect, a rim of two s'e arableparts, namely, a long-part compose of five sections permanentlyconnected together, and a short part composed of sections like a section20.

In order to put a tire onto .the rim, the short section is section. Thelo art of the rim .may then deformed su ciently to permit the tire to beput onto it, and then said long l rim section ma be restored to itsnormal 5 Then the s ort section 20 may be introduced into the spacebetweenthe ends of part. To

referably do this may require a slight teral, twisting of the shortremovable run but it can be easily done. As it is done the tongues 12 onthe ends of the long rim member will pass through the holes 23 near theends of the section 20, and the belled ends-21 of the latter will fitover the ends of the ion rim- .membei -w'hich ends are shaped lk Whensection this section'20 "has, been so inserted to come out accidentally.

'tion might be se.

disconnected from the long ape.

the long 1 e thejends of the sections '10,

into place to complete the rim, it is not liable Indeed, it takesconsiderable clever manipulation to displace it. The then com leted rimwith the tire thereon will then e put u on a wheel so that the laterallyextended bolts 81 carried by the wheel felly 30 will each pass throughthe ali'ned holes 14, '24, in the two overla p ng tongues at each joint01 the rim. The lll'll may carry .a felly'band 32 shaped to fit theinterior of this rim, whichwill insure that the rim sections remain inthe desired relation to one another. When 'niitshave been screwed ontothe bolts 31, the rim is securely locked in lplace, and as shown; thesame instrumenta itieswhich interlock with one another tohold the rimsections together being employed to hold the rim upon the wheel.

Instead.of fastening together five of these short sections and havingone of the sections 20 removable, it is possible to fasten to gatherfour of said sections to form the mawrfpart'of the rim, and .to fastentogether two 0 the sections to form the removable short part of the rim.In that event one end of the large rim member would be belled at oneend, while the-other end thereof would be an inner section end. So withtheshort removable part of the rim, one end thereof would be s sped-likean outer end section, while the other end would be shaped like an innerend'section; Fro'rn ily understood that-instead of making the rim ofsections 10 and 20, .whereof both ends of the section 20 are outersection ends, .the entire six sections mi ht be made like the sectionshown in F' that is to say, with an inner section ed at one end thereof,and an outer secfiion end .atthe other. In this event,.five s ortsections mi ht when their ends were properly interloc ed, be armanentlyconnected, and one short simi ar secarate therefrom.

Havin descri ed my invention, I claim:

1. A emounta'blewheel rim comprising a plurality of segmental channeledsections whose ends are overlap ed and are formed with parts which interock when the ends are overlapped, and means enga 'ng said interlpckingparts for fastening tem on a wheel.

'2. A demountable wheel rim comprising a plurality of segmentalchanneled sections whose ends are overla ped,the outside over lappingparts of eac section being formed with a hole, and a tongue whichextend: toward the axis of the wheel from one edg of said 1 hole,, andthe inside overlap in; part of each section having a tongue w icl passesthrou h said hole in a line substan tially paralle with the first namedtongue,- said tongues being formed to be engage by means for fasteningthe tongues and cor sequently the rim to a wheel.

this it will beread- I tuntabl'erim made up of a plurality; of 1suchi'iength ihat they may be formed from flat sheet metal strips by thestempin process, said sections being formed wit1 overlapping ends, theouter section at each joint being enlarged to such extent that. theoverlapping part of the innersection fits into said enlargement wherebythe tire receiving channel ofthe produced rim has substantiallycontinuous surlj'aoes.

4. A demountable rim composed of a plurality of segmental channeledsections whose ends overlap and are formed with interlock- 3. {a as;

ing parts which hold the segmental sections in operative relation andwhich also serve as the means through which the rim is locked on theWheel.

5. A demounta'ble rim composed of a plurality of connected segmentalchanneled sections having overlapping ends, the overlapping parts ofboth sections being formed with tongues which extend in parallelrelations toward the center of the rim, and means adjacent each jointfor engaging both tongues for locking the rim on a Wheel.

6. A demountable rim composed of a plurality of connected segmentalchanneled sections having overlapping ends, at least one of mid sectionsbeing separably connected wit adjacent sections, and means providedgmental channeled sections of least two separable connected :Y--'".I1-I1ll channeled sections having overlapping w e, the overlapping parts of)0th sections b ing Erovided with means adapted to he engaged 40 ydevices for locking the rim on a wheel.

8. A demountable rim con'ipose'tl of at least two separable connectedsegmental channeled sections having overlappinfiemls the overlappingeach (joint being ormed with inwardly di recte parallel tongues whichhave reg1stering les.

9. A demorwable rim composed of at least two. s c' .-arable connectedsegmental 50 channeled so. a ions having overlapping ends, theoverlapping parts of both sections at each joint being formed withinwardly directed parallel tongues which have reglsterarts of bothsections at ing holes, and the tongue attached to the 5 inner sectionend being formed with a flange, and the end of theother tongue beingformed to engage with and tit said flange.
